GAS-PRESSURE REGULATOR.

Specification of Letters Patent.

' Patented Feb. 18, 1908.

Application filed May 18. 1907. SerialNo. 374.460.

To all who) it may concern: g

Be it known that I, PETER. KELLER, a. citizen of the l'uited States, residing at the city of Chicago, in the county of (ooh and State of Illinois. have invented a new and useful lmprrwement in Gas-Pressure Regulators. of which the following is a specification.

My invention relates to devices for corn trolling the flow of fluids and particularly of illuminating gases through pipes.

The object thereof is to provide a simple, cheap and convenient apparatus by which the pressure of illuminating gas may be automatically.regulated and controlled and by which the volumeof such gas may be taken from the service pipes at varying pressures and delivered to the house pipes or to a particular point of combustion as, for instance, a gas stove at constant pressure.

My device further isof such a character that the standard unions used for detachably connecting piping maybe used as a casing to inclose the device and to become an actual part thereof. 5

The principles of my invention are illustrated in the drawings, in which- Figure 1 shows one form of my device as used in connection with a standard union; Fig. 2 shows another form thereof which may be connected directly to the pipingpFig. 3 is an alternative form, and Fig. 4 is an end view of the device when removed from Fig. 1, and looking toward the right.

Further describing my invention with reference to the drawings: 1 is a service pipe from which gas passes into my device.

2 is a shell or tube having a conical chamber 3 whose longitudinal axis is approximately horizontal, thereby causing the lower side 4 of the chamber 3 to be somewhat] slanted fromthe perpendicular axis. VVithin the said chamber is" contained a closure ball 5 which, under the influence of gravity,

will normally seek the lowest position at the larger end of the chamber Its movement may be stopped and it may be kept from leaving the chamber by a pin 6, as shown in Fig. 1 by a screw plug 6 as shown in Fig. 2, by a screw cap 6 as shown in Fig. 3, or by any other means. Progressionof the ball in the other direction, viz. with the flow of the the ball within the tapering wall of chamber 3. p The features thus far described are pracgas, may be stopped by pins 7 or any other suitable means, which Wlll prevent wedging tically common to the different embodiments of my invention shown in the drawings.

In Figs. 1 and 3 the shell 2 is provided with an annular flange 9 having an annular off-set portion 10. When so provided an ordinary union may be used as a setting and housing therefor without any special work either on the union or the device itself. Such union ordinarily consists of an externally threaded member 12 and a shouldered member 13. The shoulder of the last named element is adapted to be engaged by the screw ring or binding nut 15, the threads on which engage the external threads of part 12. The shouldered member 13 is usually provided with the ring or annular flange 16. And when it is desired to place my device in position therein, the off-set portion 10 of the annular flange 9 will encircle the said flange 16 and center the device in the union and the service pipe to which it may be attached. The other portion 12 of the union when placed in proper relative osition and the nut 15 is turned in place, Wi 1 be drawn against the lower side of said annular flange 9 and holdthe entire device properly centered in the piping. The

. device is thus securely inclosed against accidental or other injury, and when connected up and the device given its proper horizontal position will work indefinitely and automatically to control the flow of gas therethrough. As the pressure of gas in the mains becomes greater, the increased cur-- rent will carry the ball with it, rolling it up the incline, and thus decreasing thesize of the assage. In extreme cases the ball may be b ocked by the stop, otherwise it will constantly fluctuate with increasing and decreasing pressure to keep a constant flow through the apparatus and constant pressure in the spaces beyond. To prevent complete closing of the device grooves 16 may be provided as shown in Figs. 1 and 3, through which a certain amount of current flow will pass in any event. The closure 5 will then serve to regulate the pressures over and tinuous and constant Whenever used.

I claim and desire to secure Patent 1. In combination with a pipe union having a shouldered member and an annular flange thereon; a gas pressure regulator having a casing provided with an annular flanged l and an off-set portion adapted to encircle gas is being by Letters above the flow therethrough, which is conthe flange on the union and a closure therein, said union being adapted to act as a housing for said regulator.

2. In combination with a pipe union comprising a plurality of members and a binding nut; one of said members being shouldered and provided with an annular flange, a gas nular flange and an ofi-set portion adapted to encircle the annular flange in said member.

4. In a gas controlling device, a casing provided with a conical gas pressurechamber so laced that its longitudinal axis is substantia ly horizontal, a ball closure in said passage, and means for limiting the traverse of said closure in both directions.

5. In a gas controlling device, a casing provided .wlth a conical gas pressure chamer having its longitudinal axis in substantially horizontal position, 9. Ion 'tudinal groove throughout the len th of t e inner wall of said chamber a bal closure in said of said closure.

6. In combination with a pipe union, a gas pressure regulator comprising a casing'provided with a conical gas passage so placed that its longitudinal axis is substantially horizontal, a ball closure in said passage, and means for limiting the traverse of said closure, said union being adapted to inclose and act as ahousing for said regulator.

In testimony whereof I have hereunto set my hand this 2nd day of May A. D. 1907, in the presence of two subscribing witnesses.
